Constructive Elements Regarding the Design of a Plastic Waste Shredding Machine

ABSTRACT: 

This article presents directions to improve the process of recycling plastic waste by eliminating some steps in the flow diagram of the current recycling process. The main household plastic waste materials are P.E.T., H.D.P.E. and P.P. thus this concept aims to collect, sort and shred these into flakes to reduce the space occupied before transportation to the recycling units. As these materials are visually similar but chemically very different is important to consider all the constructive elements regarding the design of a recycling machine, such as the right sensors for identifying the polymers, blades to be able to shred them, the right unit dimension, engine, and friendly interface. This machine is a big help in a world polluted by a substantial amount of plastic waste, that represents a threat to the sustainability of our planet. The main purpose of this paper is to present the first steps in the design development of such needed machine that can help reduce the amount of plastic that ends up in landfills and oceans.

Keywords: plastic waste, shredding, sorting, recycling, machine design.
